RM2ANEFA3–Organography of plants, especially of the archegoniatae and spermaphyta . ed leaves are absent, asin Calypogeia ericetorum. The appear-ance of leaves on the outside of thetube has given rise to the incorrect assumption ^ that a vegetative point liesin an umbilicate pit at the base of the tube, and that this produces leaves.Whence could this vegetative point come ? The vegetative point of thefertile shoot is used up in the formation of the archegonia: it must thenbelong to a lateral shoot, and this leads to impossible results. Lateralshoots occasionally appear on the fertile shoot of Calypogeia

It has, however, a solid opaque shell, is umbilicate, and has an extraordinary apex which is planulate and fits like a cap on the summit of the spire. Hedley thought this apex may be a plug formed after the shedding of earlier whorls. In the same year as he proposed Menon, Hedley (Proc. Linn. Soc. N.S.W., 1900, p. 505) withdrew the name on Professor Tate s suggestion in favour of Chileutomia Tate & Cossman, a Tertiary fossil from Muddy Creek, Victoria. Though
